Today I was faced with a furnace duct cleaning challenge, Kodiak Fitness in Fort McMurray Alberta had a septic backup and it had flooded the in floor ducting.

I had advised the customer to contact a sump pump company to first draw all the liquid out of the duct system before I start the cleaning process. Duct cleaning a system with in-floor ducting provides challenges that you do not face when cleaning a suspended ducting system, such as access is only available where ever the heat register is located. In a suspended furnace duct system you can make more access holes as required.

The good side of having a in-floor ducting system is there are fewer air leaks in the system which means stronger suction from the vacuum system. Because we have limited access holes we will use a combination of the Duct Brush system and  the Air Viper system to completely clean the duct system.

The cleaning went as expected and was a success with the system completely cleaned out. To finish the cleaning process when there was a septic backup we have to fog the furnace duct system with Benefect which will kill 99.9% of all germs and bacteria.

The furnace’s were two down flow Engineered Air Systems, I pulled the fans of both furnaces and cleaned the blowers, heat exchangers and the burner assembly. I also sprayed the blowers and blower compartments with Benefect. The customer supplied the filters to be replaced in the system.

With the system completey cleaned and Benefect spray applied the system is ready to be inspected by Health Canada so the customer can continue with the planned renovations.
